Meeting Challenges of LTE Advanced through Small Cell Deployment

Juhi Bagaria and Hamid Shahnasser

Abstract—The paper focuses on how operators can meet challenges of LTE Advanced, LTE A through small cell deployment. LTE A is revolutionizing features such as Real time HD voice, video services and coverage with reduced cell drops. According to the performance targets defined by 3GPP LTE A will boost data rates from 150Mbps (LTE-Rel8) to 1Gbps. It will also ensure higher cell throughput, lower cost per bit, increased cell edge performance and upsurges of network efficiency. The answer lies in small cell deployment. The world is scaling down its parameters and so are the cell sites, allowing people to get more connected. Giant macro cell towers are being taken over with smaller units as also carriers are increasingly relying on small cell options. Small cells enhance cellular coverage and capacity in homes, enterprises, buildings and rural public areas. “They are low power wireless access points ranging from femto cells to microcells”. This paper will review the enhancements that LTE Advanced will bring to the mobile network and the vital role that small cells play in realizing the advancement.
